Available in PDF, EPUB and Kindle. Book excerpt: This book is an excellent resource for scientists, political decision makers, and students interested in the impact of peatlands on climate change and ecosystem function, containing a plethora of recent research results such as monitoring-sensing-modeling for carbon–water flux/storage, biodiversity and peatland management in tropical regions. It is estimated that more than 23 million hectares (62 %) of the total global tropical peatland area are located in Southeast Asia, in lowland or coastal areas of East Sumatra, Kalimantan, West Papua, Papua New Guinea, Brunei, Peninsular Malaysia, Sabah, Sarawak and Southeast Thailand. Tropical peatland has a vital carbon–water storage function and is host to a huge diversity of plant and animal species. Peatland ecosystems are extremely vulnerable to climate change and the impacts of human activities such as logging, drainage and conversion to agricultural land. In Southeast Asia, severe episodic droughts associated with the El Niño-Southern Oscillation, in combination with over-drainage, forest degradation, and land-use changes, have caused widespread peatland fires and microbial peat oxidation. Indonesia's 20 Mha peatland area is estimated to include about 45–55 GtC of carbon stocks. As a result of land use and development, Indonesia is the third largest emitter of greenhouse gases (2–3 Gtons carbon dioxide equivalent per year), 80 % of which is due to deforestation and peatland loss. Thus, tropical peatlands are key ecosystems in terms of the carbon–water cycle and climate change.

Download or read book Guidelines for Using Activated Sludge Models written by Leiv Rieger and published by IWA Publishing. This book was released on 2012-09-14 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mathematical modelling of activated sludge systems is used widely for plant design, optimisation, training, controller design and research. The quality of simulation studies varies depending on the project objectives, finances and expertise available. Consideration has to be given to the model accuracy and the amount of time required carrying out a simulation study to produce the desired accuracy. Inconsistent approaches and insufficient documentation make quality assessment and comparison of simulation results difficult or almost impossible. A general framework for the application of activated sludge models is needed in order to overcome these obstacles. The genesis of the Good Modelling Practice (GMP) Task Group lies in a workshop held at the 4th IWA World Water Congress in Marrakech, Morocco where members of research groups active in wastewater treatment modelling came together to develop plans to synthesize the best practices of modellers from all over the world. The most cited protocols were included in the work, amongst others from: HSG (Hochschulgruppe), STOWA, BIOMATH and WERF. The goal of the group is to set up an internationally accepted framework to deal with the ASM type models in practice. This framework shall make modelling more straightforward and systematic to use especially for practitioners and consultants. Additionally, it shall help to define quality levels for simulation results, a procedure to assess this quality and to assist in the proper use of the models. The framework will describe a methodology for goal-oriented application of activated sludge models demonstrated by means of a concise guideline about the procedure of a simulation study and some illustrative case studies. The case studies shall give examples for the required data quality and quantity and the effort for calibration/validation with respect to a defined goal. The final report will include an extended appendix with additional information and details of methodologies. Additional features in Guidelines for Using Activated Sludge Models include a chapter on modelling industrial wastewater, an overview on the history, current practice and future of activated sludge modelling and several explanatory case studies. It can be used as an introductory book to learn about Good Modelling Practice (GMP) in activated sludge modelling and will be of special interest for process engineers who have no prior knowledge of modelling or for lecturers who need a textbook for their students. The STR can also be used as a modelling reference book and includes an extended appendix with additional information and details of methodologies. Scientific and Technical Report No. 22
Download or read book Instrumentation Control and Automation in Wastewater Systems written by Gustaf Olsson and published by IWA Publishing. This book was released on 2005-04-30 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Instrumentation, control and automation (ICA) in wastewater treatment systems is now an established and recognised area of technology in the profession. There are obvious incentives for ICA, not the least from an economic point of view. Plants are also becoming increasingly complex which necessitates automation and control. Instrumentation, Control and Automation in Wastewater Systems summarizes the state-of-the-art of ICA and its application in wastewater treatment systems and focuses on how leading-edge technology is used for better operation. The book is written for: The practising process engineer and the operator, who wishes to get an updated picture of what is possible to implement in terms of ICA; The process designer, who needs to consider the couplings between design and operation; The researcher or the student, who wishes to get the latest technological overview of an increasingly complex field. There is a clear aim to present a practical ICA approach, based on a technical and economic platform. The economic benefit of different control and operation possibilities is quantified. The more qualitative benefits, such as better process understanding and more challenging work for the operator are also described. Several full-scale experiences of how ICA has improved economy, ease of operation and robustness of plant operation are presented. The book emphasizes both unit process control and plant wide operation. Scientific & Technical Report No. 15

Available in PDF, EPUB and Kindle. Book excerpt: "[A] compelling debut…Townsend's writing [is] full of fresh turns of phrase and keen insights." —Ayana Mathis, New York Times Book Review Fourteen-year-old Audrey Martin, with her Poindexter glasses and her head humming the 3/4 meter of gospel music, knows she’ll never get out of Kentucky—but when her fingers touch the piano keys, the whole church trembles. Her best friend, Caroline, daydreams about Hollywood stardom, but both girls feel destined to languish in a slow-moving stopover town in Montgomery County. That is, until chance intervenes and a booking agent offers Audrey a ticket to join the booming jazz scene in Harlem—an offer she can’t resist, not even for Caroline. And in New York City the music never stops. Audrey flirts with love and takes the stage at the Apollo, with its fast-dancing crowds and blinding lights. But fortunes can turn fast in the city—young talent means tough competition, and for Audrey failure is always one step away. Meanwhile, Caroline sinks into the quiet anguish of a Black woman in a backwards country, where her ambitions and desires only slip further out of reach. Jacinda Townsend’s remarkable first novel is a coming-of-age story made at once gripping and poignant by the wild energy of the Jazz Era and the stark realities of segregation. Marrying musical prose with lyric vernacular, Saint Monkey delivers a stirring portrait of American storytelling and marks the appearance of an auspicious new voice in literary fiction.
